19 Claims.

This invention relates to automatic mechanism for raising and loweringthe cover of a container as it is slid out and moves back within akitchen cabinet or elsewhere, and has for an object to provide a simpleinexpensive device of this class. Another object is to provide such adevice which is adapted to be installed with a platform and itssupporting guide or track. A further object is to provide such a devicethat is proof against being attached incorrectly. Yet another object isto provide a mechanism for actuating the cover which is constructed toinsure a definite and predetermined timing of the cover. Still anotherobject is to provide cover actuating mechanism in rear of the containerso as not to interfere with the filling of the container or be in dangerof catching on anything.

In my Patent #2,247,232 dated June 24, 1941, for Container and supporttherefor, is shown and described a platform containing a receptaclewhich moves out and into a wall opening in response to opening of adoor.

According to this invention lever mechanism is sold and installed withthe platform and container as a. part of the combination, whereby thetiming and opening of the cover is correctly set for convenientoperation, and elimination of labor in installation to a desirableminimum is an important factor.

Fig. 11 is a side view from the right of the device as shown in Fig. 2.

Referring to Fig. 1. The platform I0 is preferably mounted on rearrollers H and the front roller II as is described in the aforesaidpatent.

A container I2 is located on the platform as described in prior patent,and is provided with a cover l3, pivotally secured to the container atl5, from which rearwardly extends a projection l4. Pivotally secured at|6-a to the projection I4 is the link l6 which extends downwardly asillustrated. Pivoted at l1 to the platform is lever l8 whose upper endis pivoted at 22 to the link IS, the lower end of which is pivoted at 20to a stationary support 2|. This support is secured to the floor orother stationary support and extends around and in back of the platformin the laterally mid-portion thereof where it may serve as an abutmentto limit inward movement of the platform. The lower end of the link I6is pivotally secured at 23 to the lever 18. On moving the platformforwardly these links take the position shown in dotted lines in Fig. 1in which the corresponding parts have been designated with the sameidentifying numerals. As will be seen from Fig. l, sliding the platformforward causes the pivotal connection 22, between the lever 18 and linkH! to be lowered. At the same time the pivotal connection 23 at thelower end of the link I6 is lowered causing the link IE to pull down onthe cover extension I 4 and open the cover I3 of the container l2, inresponse to forward movement of the platform Hi. It will be understoodthat the lever l8 and link H! are of such length that when the platformis in its forwardmost position this lever and link shall not be inalignment, in order that on inward movement of the platform the leverand link may be raised to their full line positions in Fig. 1 withoutdifficulty. Any well known or convenient mechanism for moving theplatform outwardly is adapted for use with the embodiment thereinillustrated. Such may include a connection between the platform and thedoor as is disclosed in the prior patent referred to above.

In Fig. 2 a similar platform l0 contains a similar container l2 having acover l3 pivoted at l5. Unlike the embodiment illustrated in Fig. 1,that shown in Fig. 2 depends on a link 24 being pushed upwardly to raisethe cover l3 by means of a pivotal connection 25 to a cover extensionand located between the cover pivot l5 and the body of the container l2.Secured to a support 29, which is preferably fixed with respect to theplatform I0, is a lever 21 pivoted at 28 to said support 29 and havingits adjacent end 26 pivotally connected to the link. 24. The oppositeend of the lever 21 is pivoted at 3| to the link 30 whose lower end ispivotally secured at 32 to a stationary support which does not move withthe platform.

Only the link 24 and lever 21 in Fig. 2 are located centrally of theplatform, whereas in Fig. 1 the links and lever are located centrally ofthe platform. By using the abutment support 2| of the type shown in Fig.1 it is not necessary to use a two part link connected thereto, one partbeing on each side of the platform, but instead the link connected tothe stationary abutment is centrally of the platform. In Fig. 2 as thelever 21 and link are lowered at their pivotal connection 3|, theconnection 26 between the link 24 and lever 21 is raised, causing theconnection 25 to be raised and the cover to be opened as shown in dottedlines in Fig. 2.

In Fig. 3 is shown a similar platform and container which are actuatedby a pedal 33 located adjacent the forward part of the platform whenretracted, the pedal 33 being shown in Fig. 3 as being slightly inadvance of the platform in the full line position. This pedal ispivotally connected at 34 to a stationary support which does not movewith the platform and the pedal lever extended rearwardly beyond theconnection 34 to a point adjacent the rear of the platform where it isshown as being provided with an upstanding portion 35 for connection at36 to the arm 31 of a bell crank lever 38 pivoted at 39 to a stationaryabutment 46, as is shown in both Figs. 3 and 4. The other end of thelever 38 is pivoted at 4| to the lever 42 whose lower end is pivotallysecured at 43 to the container l2, A tension link 45 is pivotallysecured between a connection 44 on the lever 42 and an upper con nection46 on a rearward extension of the cover, so that as the platform ismoved forward the tension link 45 is pulled down opening the cover.While the pedal is shown in Fig. 3 as actuating a link and levermechanism of the type shown in Fig. 1, it will be apparent that the samepedal may actuate a link and lever mechanism for opening the cover inthe manner shown in Fig. 2.

Figs. 5 and 6 show a door 41 extending across an opening and havingsecured on the inner face thereof a projection 48, (Fig. 6); a link isconnected at one end to a pivot 49 on the extension 48 while theopposite end of the link 50 is pivotall secured at 52 to the undersideof the platform ID. The door 41 is hinged on a vertical axis 5| so thaton opening the door the link 56 pushes the platform forward while onreclosing the door the link 56 pulls the platform rearwardly. Anadvantage of this type connection between the door and the platform overthat described in the aforementioned patent is that greater forwardmovement of the platform is obtainable for a given angular movement ofthe door. As shown in Fig. 5 the platform is provided with a stationaryabutment and support of the type shown in Fig. 1 and the container coveris opened by means of a lever mechanism of the type illustrated in Fig.2. It will be understood however that a Fig. 1 or 3 type mechanism maybe used for opening the cover when the platform is moved outwardly byopening the door.

The platform and guide shown in Fig. 7 may be of the type thereinillustrated or of any other convenient form such as that shown in saidpatent referred to. Located beneath the platform I0 is a wall 53 fixedwith respect to the platform support and containing an inclined cam slotor guide 54, shown in Fig. 8 as extending forwardly and upwardly fromits rear portion. A lever 56 is secured to the cover so that as theplatform is moved forward the cover is raised by its actuating rodmoving upward. This rod 56 extends from the cover down through anopening or hole 51 in the platform I0 (Fig. 7). Its lower end portionhas a rearward extension 56 as shown in Fig. 8 as being preferablyprovided with a roller 55 for lessening friction as the rod moves in theslot 54. Inasmuch as the container and the platform are desirably movedto a position in front of the position of the platform when retracted,and since the wall 53 should not preferably extend in front of theforward end of the platform when retracted, it may be understood thatthe rearward extension 56 on the lower end of the rod 56 permits thecover to continue its opening movement when the platform is furtherforward than would be the case if such rearward extension were notpresent and the roller 55 were attached directly to the end of the rod56.

In Fig. 9 is shown a wall 58 corresponding to the wall 53 in Figs. 7 and8, except that the cam slot 59 in the wall 58 slopes forwardly anddownwardly with the result that a rod 60 connected to the cover ispulled down on sliding the platform forward to open the cover accordingto the type of cover actuating connection shown in Fig. 1. The coveractuating lever 60 in Fig. 9 will preferably have a rearward extension6i! on its lower end for the same purpose mentioned in connection withthe cover actuating lever in Figs. 7 and 8. In both Figs. 8 and 9 thecover actuating lever passes through a hole in the platform since thecam slot is located beneath the platform and the sides of the holethrough which the cover actuating rod passes serve as a guide for thiscover actuating rod. The portion of the cover actuating rod whichengages in the cam slot 59 is preferably provided with an anti-frictionroller or other appropriate mechanism for reducing friction of the rodmoving in the cam slot. In both Figs. 8 and 9 the guide slot ispreferably wide enough so that on moving the platform in one directionthe roller engages on the one side of the slot, whereas in moving theplatform in the opposite direction the roller engages the other side ofthe slot.

In Fig. 10 the container I2 is mounted to slide outwardly without theaid of any platform, a suitable supporting post 6| carries a lazy-tongtype lever mechanism 62 to the outer end portion of which the containerI2 is pivotally secured as illustrated. On pulling the container outwardit is supported by the lever mechanism 62 and on retracting thecontainer the lever mechanism 62 tends to collapse in the usual wellknown manner. For opening the cover l3 in response to outward movementof the container, a cover actuating rod or link 63 is connected to thecover in the general manner shown by Fig. 1. The cover actuating rod 63is relativel short being attached to a pivotal connection 64 so that asthe container is moved outward the connection 64 tends to move downwardopening the cover; the converse occurs on retracting the container.

An especial advantage of the constructions illustrated is the locationof the link and lever mechanism in rear of the container where it is outoif the way and inconspicuous. The lever and link mechanism illustratedis usually sold with the container and platform as a unit forinstallation. It is relatively fool-proof and certain and reliable.

The platform of Figs. 1 to 7 and the lazy tongs of Fig. 10 are both asupporting means for the container. The link and lever mechanism [9 andIs in Fig. 1 for example may be regarded as a means for automaticallymoving the cover actuating link l6, which means is engaged by astationary support 2|, The pivot l1 functions as a guide for the linkI6. In Figs. '7 to inclusive, are also found means for automaticallymoving the cover actuating rod or link and a stationary support engagedthereby. The edges of the hole 51 in Fig. 7 function as a guide for thecover actuating link 56, whereas in Fig. 10 such guide for the link 63is provided by the pivot pin (unnumbered) but shown on the side of thecontainer. The container used in a kitchen for waste materialcustomarily has an inner and removable container within it as iswell-known.
